Functions of the Skin





A basic purpose of skin is to provide a waterproof, protective covering for the body's complex internal environment. The skin also plays key roles in helping to maintain the circulatory and nervous systems.





Because it contains thousands of small blood vessels, or capillaries, the skin helps transport blood throughout the body. In addition to providing oxygen and nutrients to cells within skin layers, the skin's blood vessels aid in regulating body temperature. By expanding on a hot day, skin capillaries help the body to shed internal heat. On a cold day, constricting capillaries help the body to retain heat.





Nerve cells in the skin form the body's first contact with the outer world. At the moment of birth, an infant's first experiences of the physical world are perceived through the sense of touch. Through nerve cells, the skin receives and transmits signals for touch, pain, and change of temperature.





UV rays from the sun stimulate a biochemical process that converts a body chemical in the skin to Vitamin D. Vitamin D helps the body absorb calcium.





The skin is also a major contributor to the body's immune system. In addition to being the first line of defense in keeping out bacteria, viruses, and other organisms that invade the body, the skin is home to enormous quantities of T-lymphocytes, or T-cells. T-cells attack and destroy bacteria, fungi, viruses, parasites, toxins, and cancerous cells that can cause disease.1.
